Problem

Branch A conducts charge into a junction at a rate of

150\,\text{C}

every minute, branch B carries

1.2\,\text{A}

away from the junction, and branch C delivers

0.50\,\text{A}

into the junction. What current flows in branch D if it carries charge away from the junction? (a)

3.0\,\text{A}

away from the junction (b)

1.8\,\text{A}

away from the junction (c)

150\,\text{A}

away from the junction (d)

1.8\,\text{A}

into the junction
